Aircraft having a system for attaching an element to a fuselage and having a lightning protection screen

Abstract

An attachment system for fastening an element to an aircraft fuselage, wherein the attachment system has a plate having a first face and a second face oriented towards the fuselage, and wherein the plate is fastened to the fuselage, a fitting fastened to the element and having a contact face in contact with the first face, and at least one fastening bolt having a screw and a nut, wherein the head of the screw is housed in the plate on the side of the second face, and wherein the nut is screwed to the screw, sandwiching the plate and the fitting. Also an aircraft with such an attachment system.

Claimed is: 
     
         1 . An aircraft comprising:
 a fuselage, an element and at least one attachment system for fastening the element to the outside of said fuselage, the attachment system having:
 a plate having a first face and a second face oriented towards the fuselage, and wherein the plate is fastened to said fuselage, 
 a metal fitting fastened to said element and having a shoe with a contact face in contact with the first face, and 
 at least one fastening bolt having a screw and a nut, wherein a head of the screw is housed in the plate on the side of the second face and wherein the nut is screwed to the screw, sandwiching the plate and the shoe of the fitting. 
   
     
     
         2 . The aircraft according to  claim 1 , wherein the plate comprises an electrically insulating material arranged to prevent a passage of current. 
     
     
         3 . The aircraft according to  claim 1 , wherein the plate comprises a thermally insulating material arranged to limit a passage of heat. 
     
     
         4 . The aircraft according to  claim 1 , further comprising:
 an intermediate plate disposed against the second face of the plate and configured to be disposed against the fuselage.   
     
     
         5 . The aircraft according to  claim 4 , wherein the intermediate plate comprises the same material as a material constituting the plate. 
     
     
         6 . The aircraft according to  claim 1 , wherein the plate is fastened to the fuselage by a plurality of bolts, wherein each bolt has a screw with a head and a nut, wherein, for each bolt, the plate has a through-piercing and the fuselage has a through-orifice aligned with the piercing,
 wherein, for each bolt, the screw of said bolt passes through a piercing and an associated through-orifice so as to sandwich the plate and the fuselage between the head of the screw of said bolt and the nut of said bolt, and   wherein the piercings of the plate are arranged such that there is no contact between the shoe and the heads of the screws.   
     
     
         7 . The aircraft according to  claim 6 , wherein the plate is wider than the shoe and the piercings are on an outside of and at a distance from the shoe.
